(36) باب مَسْأَلَةِ الشَّهَادَةِ .
It was narrated from 'Uqbah bin 'Amir that the Messenger of Allah (ﷺ) said:
"There are five things, whoever dies of any of them is a martyr. The one who is killed in the cause of Allah is a martyr; the one who dies of an abdominal complaint in the cause of Allah is a martyr; the one who dies of the plague in the cause of Allah is a martyr; and the woman who dies in childbirth in the cause of Allah is a martyr."
